DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work transfer reversing device suitable for reversing and supplying a hot work from a casting process, for example, to a next process, for example, a press process, as it is.

[0002]

2. Description of the Related Art If it is possible to invert a work in a high heat (for example, 1200 ° C.) or low heat state in a previous process from a supply posture and supply the work directly to a next process, the temperature of the work is controlled to room temperature or the like in an intermediate process. This eliminates the need for extra work, thereby improving work efficiency. In this case, in the prior art, as a means for reversing the work, the work supplied to the receiving table at a predetermined position by a chute or the like is reversed by a device combining various mechanisms, and the work is transferred to the next process side by another transfer device. Then, a method of inserting the sheet into the supply point is adopted. Therefore, the structure of the device and the structure of the transfer control are complicated. In addition, since the workpiece has high or low heat, each element and control device of the apparatus must be special and expensive.

On the other hand, as a known technique relating to the transfer reversal of a work, there is, for example, JP-A-10-157833. This "work transfer direction reversing device" reverses a work that has been suctioned and held by an air chuck and sent vertically, and transfers the work horizontally to a transport member disposed along the horizontal direction. is there. The work is sucked at the bottom on the receiving table and temporarily supported vertically, then it is laid down sideways by a pusher that presses the top of the work horizontally, and is fed horizontally on the transfer member by an inertia chute. This is sent to the next process side by the movement of the transport member.

[0004]

As described above, a considerably complicated and expensive apparatus and equipment are required for reversing a workpiece sent by high heat or cold heat and transferring it to a distant next process side. I do. In addition, if these devices are used, it is difficult to supply them at high speed to the next step. On the other hand, the above-described known technology can supply a relatively high-speed work, but is difficult to apply to a hot or cold work. That is, for example,
It is not possible to use suction means such as magnet suction or vacuum suction on the receiving surface at the drop position for a hot work. Further, in the case of a work having a high heat or the like, it is difficult to stabilize the posture of the supply work with this known technique because the work cannot be gripped and supplied by the air chuck. In addition, the inverted work is not directly pressed by the pusher, but is sent onto the conveying member using a progress chute, so that the transfer means becomes complicated. Further, there is no assurance that the work inverted by the pusher is correctly oriented horizontally on the conveying member.

The present invention solves the above-mentioned problems and the like. A high-heat or low-heat work can be reversed and fed to the next process side at a high speed while keeping the reversing posture stable, and the apparatus structure is relatively simple. It is an object of the present invention to provide a work transfer reversing device that can be implemented at low cost.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a work transfer for reversing a work supplied vertically or horizontally to a receiving table and transferring the work to a next process side remote from a supply position. A reversing device, comprising a clamp unit for gripping and releasing the supplied work, a pusher unit for pressing the work to perform the reversal, and supporting the reversed work and extending to the next process side. A work transfer reversing device is provided which includes a transfer table to be provided and a transfer control unit for transferring the clamp unit and the pusher and releasing the work holding of the clamp unit at an appropriate position.

More specifically, there is provided a work transfer reversing device for transferring a work dropped and supplied vertically onto a receiving table while maintaining a high heat or a low heat to a next process side distant from a drop position and supplying the work by inverting the work. A clamp section for gripping and releasing the work, a pusher section for turning the work and pressing the work, and supporting the work which has been turned over and turned sideways on the V-groove and extending to the next process side. A V-rail, and a transfer control unit that controls the transfer of the clamp unit and the pusher unit. The transfer control unit releases the clamp of the work gripped by the clamp unit and transferred onto the V-rail. A work for operating the pusher to push the work toward the next process while the work is supported by the V rail while pressing the work with the pusher. And it constitutes a transfer turner device. Further, the pusher portion has a contour shape in which a fingertip portion that contacts a side surface of a vertically placed work and a pressing surface that contacts an end surface of a horizontally placed work are integrally formed. The V groove of the V rail has an angle of 120 ° to 1 °.
It is characterized by being formed at 40 °.

When the work is hot or cold, it may not be possible to supply the work by holding it with an air chuck or the like. For example, the work is dropped and supplied by a shooter or the like. This work is gripped at the supply position by the clamp unit and sent to the transfer table side. In this case, in the present invention, the clamp section and the pusher section are transferred together. The clamp unit releases the grip of the work on the transfer table, and the pusher unit abuts and engages the work to invert the work. The pusher unit presses the inverted work, sends the work to the next process side along the transfer table, and inserts the work into the next process. As described above, the present invention does not use suction means using air or a magnet or special sensors.
Therefore, it can be implemented relatively inexpensively. In addition, the pusher unit performs reversal, pressing, and transfer, so that the speed can be increased.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a work transfer reversing device according to an embodiment of the present invention. In the following description, a case will be described in which the work is supplied with high heat from the previous process and the supply posture is vertical.
Also, the case where the work is a round bar and the case is a V rail having a V groove will be described. However, the present invention is not limited to these conditions. FIG. 1 shows an overall schematic structure of a work transfer reversing device of the present invention. The work transfer reversing device 1 is roughly divided into a clamp portion 2,
It comprises a pusher unit 3, a V-rail 4, a transfer control unit 5, and the like. The work 6 is sent from the previous process at a high heat of 1200 ° C., for example. Further, as shown in FIG. 4, the work 6 is dropped from the shooter 7 in a vertical posture and supplied onto the receiving table 8. Of course, the pedestal 8 is made of a heat-resistant material, and portions of the clamp 8, the pusher 3, the V-rail 4 and the like, which will be described below, that come into contact with the work 6 are formed of a heat-resistant material.

As shown in FIGS. 1 and 2, the clamp 2 includes an arm 9, a holding block 10 for heat-resistant material fixed to the tip of the arm 9, and a rotating mechanism 11 for rotating the arm 9.
Etc. Note that the arm 9 is a main body 2 of the transfer control unit 5.
2 is pivoted on its proximal end. The grip block 10 is fixed to the distal end side of the elongated arm 9, and a V-groove portion 12 for gripping the work 6 is formed. The turning mechanism 11 includes a pin 13 for pivotally supporting the base end of the arm 9, a link mechanism 14, an actuator 15, and the like.
Is configured to open and close the arm 9 by the operation of. These are provided on the main body 22 side.

As shown in FIGS. 1 and 2, the pusher section 3 supports the operation section 18 made of a heat-resistant material integrally forming the fingertip section 16 and the pressing surface 17, and the operation section 18 via a support pin 19. The support block 20 is fixed to the main body 22. The fingertip portion 16 has a cross-sectional shape protruding forward in the shape of a fingertip, and has a shape in which the tip thereof abuts and engages the side surface of the work 6. Also, the pressing surface 17
Consists of a flat surface having an area where the end surface (bottom surface) 6a (shown in FIG. 4) of the work 6 turned upside down can abut.

The V-rail 4 is a carrier table which is provided adjacent to the receiving table 8 as shown in FIG. 4 and extends at the same level along the horizontal direction to the next process side, as shown in FIG. A V groove 21 is formed on the upper surface. The angle of the V-groove 21 may be an appropriate angle, but is formed at about 120 ° to 140 ° in order to stably support the work 6 of various sizes. Of course,
It is not limited to this. It is desirable that the V groove 21 be subjected to heat treatment.

As the transfer control section 5, for example, the one shown in FIG. 1 is adopted, but of course the present invention is not limited to this. That is, a main body 22 that supports the clamp unit 2 and the pusher unit 3, a guide rail 23 that slidably supports the main body 22, an actuator 24 that reciprocates the main body 22 along the horizontal direction, 15, 24
And a control unit 25 for controlling the operation of the controller.

Next, the operation of reversing and transferring the work 6 by the work transfer reversing device 1 of the present invention will be described with reference to FIGS. First, as shown in FIG. 4, the work 6 is dropped and supplied from the shooter 7 in a vertically oriented state. in this case,
In advance, the arm 9 of the clamp unit 2 stands by so that the V-groove unit 12 comes to the drop position of the work 6 with the grip block 10 opened.

The work 6 that has fallen from the shooter 7 is supported vertically by contacting the end surface 6a of the work 6 on the receiving table 8. In this state, as shown in FIG. 5, the actuator 15 of the clamp unit 2 operates the rotation mechanism unit 11 and the V
The work 6 is gripped by the groove 12. In this state, the pusher unit 3 is disposed at a position slightly away from the work 6 as shown in the figure.

Next, as shown in FIG. 6, the actuator 24 of the transfer control unit 5 operates to move the clamp unit 2 and the pusher unit 3 through the main body 22 in the transfer direction of the work. Since the work 6 is gripped by the clamp unit 2, the work 6 is transferred to a position above the V rail 4 in a vertically placed state.

Next, the actuator 15 of the clamp unit 2 is operated at an appropriate predetermined position on the V rail 4, and the arm 9 is opened via the rotating mechanism 11 in the grip release direction. As a result, the work 6 is in a free state, and the pusher section 3 can be brought into contact with the work 6 without being hindered by the clamp section 2. That is, by operating the actuator 24 and further moving the main body 22, the pusher 3 is attached to the side surface of the work 6 which is free on the V rail 4.
The tip of the fingertip 16 of FIG. In this state, the work 6 is pressed by applying a pressing force to the pusher unit 3, falls down on the V rail 4 sideways as shown in FIG. 7, and is stably held on the V groove 21 of the V rail 4. When the pusher unit 3 is further advanced, the pressing surface 17 of the pusher unit 3 hits the end surface 6a of the work 6. When the pusher unit 3 is further advanced, the work 6 is pushed later by the pressing surface 17 and moves on the V rail 4 next. It is transferred toward the process side. When the transfer and insertion to the next process are completed, the pusher unit 3 and the like are returned to the original positions, and the same transfer reversal operation is repeatedly performed.

As is apparent from the above description, according to the work transfer reversing device 1 of the present invention, the work 6 dropped and supplied is simply reversed by the movement of the clamp unit 2 and the pusher unit 3 by the transfer control unit 5 and the like. The transfer is performed as it is,
In addition, since it is stably supported by the V rail 4, it can be supplied to the next process side at a very high speed, and the working efficiency can be improved. Further, since no special equipment is used at all for the work 6 having a high heat, the apparatus can be simplified and implemented relatively inexpensively.

In the above description, the work 6 is made of a material having a high heat. However, the work 6 may be made of a cold material, and may be of a normal temperature. In addition, the work 6 is supplied in a vertical direction in advance, but may be in a horizontal direction. Further, a flat carrier may be used instead of the V rail 4, and a flat carrier is convenient when the work 6 is fed vertically. Although the work 6 is a round bar, it may be a square bar or another shape.

[0020]

According to the work transfer reversing device of the present invention,
Work of any shape can be inverted and transferred to the next process side at high speed while maintaining high or low temperature, improving work efficiency, and being simple and inexpensive, and capable of flexibly adapting to changes in work shape and dimensions. Is raised.
